Abstract
A method for production of a membrane/electrode unit for a fuel cell is disclosed. The conducting polymer membrane is compressed with two electrodes until a given compression is achieved. The method permits an increase in resting voltage of the membrane/electrode unit in use, the amount of damage during production is reduced, and a constant thickness within a production run is achieved.
